Chat Summary Tuesday, May 16, 2017 In our first week 2 chat session. Week 1 grades were grades were discussed. Professor offered us some redemption. If we go over our quiz 1 and rework the problems, once it is understood, email him that you now understand the concepts. Your quiz score will no change, but could possibly help your grade at the end of the class. Homework problems were assigned: CH. 5 – 31; Ch. 6 – 35; CH. 7 – 1, 3, 11, 19; Ch. 8 – 5, 13, 25; Ch. 9 – 5. We went over Probabilities; Las Vegas games are designed for the house to win more often than players. We also discussed binomial distributions; see page 244. We went over that formula using a table in the book on page 984. Why re-invent the wheel? Thursday, May 18, 2017 In our second chat session, the professor discussed the thread and how it will be much more helpful if we post using our jobs and experiences as examples. Last time we discussed simple probabilities, discrete and continuous variables, and binomial distribution. In the current session, we discussed Poisson distribution. Poisson is about discrete variables – those you can count on your fingers. A finite number. The number of events or occurrence within a period or interval. There are several elements of formula. Simon Poisson developed this in Paris, France. We also worked out several problems to better understand Poisson. Normal Distribution – Is the most important of any of the distributions! Many things in nature or industry – you can use normal distribution to describe them. We went over the bell curve and how on answer on the graphs. Central Limit Theorem was discussed–

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
